Medallions of Pork Tenderloin in Tarragon/Mustard Sauce

I had picked up an assortment of different potatoes (purple, pink, a couple of different kids of yellow) at last weekend’s farmers market, and had planned on maybe doing a mayo-less potato salad with something like steak. However, the more I thought about it, the more I wanted the flavors of the potatoes to stand on their own. I figured any “salad” I’d make with them would do nothing except to mask the flavors. When you have quality ingredients, simple preparation is usually better. Eventually, I settled on pork tenderloin medallions in a tarragon/mustard sauce. It paired beautifully with the potatoes, which I parboiled and then tossed in olive oil salt, and pepper, and then baked in a 400 degree oven until they were crispy. Usually, I’d add some garlic and shallots to the potatoes as well, but in this case, I felt it would distract from the flavor. Your mileage may vary, and you may enjoy the dish more making those additions.

Medallions of Pork Tenderloin in Tarragon/Mustard Sauce
recipe by David Sisk

2 pork tenderloins (not frozen)
4 to 5 T Dijon mustard, creamy (no seeds)
1/2 cup dry white wine
2 shallots, minced
1/2 pint heavy cream
4 T fresh tarragon, minced, or 2 T dried (I used half this amount)
Fresh parsley
Olive oil
Coarse kosher salt
Freshly-ground black pepper
1 T fresh whole tarragon, or 1 t dried, for garnish

Pork tenderloins will look like long narrow cones of meat. Wipe dry and, with a very sharp knife and your fingers, cut away as much fat, membrane and tendon as you can without destroying the tenderloin. Slice tenderloins into medallions, about 1/2” thick.

Heat 1 t olive oil in a large cast-iron skillet; you want only the thinnest layer of hot oil on the bottom of the pan. Brown the pork over medium-high heat, taking care not to work with so many medallions as to reduce the heat; three skillet-loads should do it for two tenderloins. Season lightly with salt and freshly-ground black pepper. You want to make sure that the pork is gray-brown on the outside but still tender; add more olive oil to the skillet as necessary. Remove pork to a warm serving dish and cover.

Deglaze the pan with the wine, scraping any brown bits into the mixture. Reduce heat to low. Add the shallots and stir frequently until they’re tender; let the wine reduce by about half. Add the mustard, stirring it into the wine mixture. Then add the cream, stirring well. Continue stirring constantly, especially the sides of the skillet where the sauce will tend to stick. The sauce will reduce; let it go to about half of what it was, or slightly more if you prefer (as you reduce the sauce, it will get more concentrated). Correct seasoning with more tarragon and pepper if necessary.

When sauce is reduced to the consistency you like, return the pork to the sauce for a few minutes, still stirring constantly. When the pork is heated through, pour pork and sauce back into the warm serving dish. Serve with crispy potatoes, green salad and a dry, full-bodied white wine. This recipe makes enough for four people who are very polite and not terribly hungry, or three people who really enjoy each other’s company, or two people who like to eat and are ready for something different. Since pork tenderloins are normally sold 2 to a package, it’s easy to multiply the recipe.

It is not difficult to grow fresh tarragon. If you decide to try, put it in an area where there are no other plants; it will get quite large and bushy.

    This looks a h.. of a lot better than the prefab pizzas I grabbed from the store on my way to the cashier…. Wish I was there to join you

    This looks like a good ol’ hearty meal, and the kinda thing that I’d make myself at home. I could imagine myself getting into trouble by trying too hard to balance the mustard flavour with the tarragon. I think if you got this right, and it seems as if you have, this will be a very good eat. The roasties look great, just by looking at them I can tell you’ve got them perfect, and I can hear the crunch they’d make when I ate one whole.
